Changelog

Sourced from cryptography's changelog.

3.2 - 2020-10-25

* **SECURITY ISSUE:** Attempted to make RSA PKCS#1v1.5 decryption more constant
  time, to protect against Bleichenbacher vulnerabilities. Due to limitations
  imposed by our API, we cannot completely mitigate this vulnerability and a
  future release will contain a new API which is designed to be resilient to
  these for contexts where it is required. Credit to **Hubert Kario** for
  reporting the issue. *CVE-2020-25659*
* Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL
  will need to upgrade.
* Added basic support for PKCS7 signing (including SMIME) via
  :class:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder`.
.. _v3-1-1:
3.1.1 - 2020-09-22

• Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1h.
